23 Claims.

This invention relates to lasting machines and is herein illustrated asembodied in a machine for lasting the toe ends of shoes. The inventionis further illustrated by reference to the lasting 5 of shoes of a typein which the margin of the lasted upper extends throughout its width ingenerally parallel relation to the bottom of the last over an insole onthe last, but it is to be understood that in various aspects it is notlimited tomeans for lasting shoes of that particular type or to meansfor lasting the toe ends of shoes as distinguished, for example, fromthe heel ends.

Under some conditions, especially in toe-end lasting, it is advantageousfor the operator of a 15 lasting machine to have full control of thelasting means in the more critical portion, at least, of the lastingoperation, so that the upper of each shoe may be subjected to suchspecial treatment as observation may indicate to be desir- 20 able. Thepresent invention, in one aspect, pro vides a machine affording suchcontrol of the lasting means and yet so constructed that a portion ofthe lasting operation for which no special skill is needed may beperformed by power. For

25 the purposes in 'view the construction herein shown comprisestoe-lasting wipers which are movable by the operator to wipe the upperheightwise of the last and to wipe its margin inwardly over an insole onthe last, but are thereafter 30 movable by power automatically to applycompacting pressure to the overwiped margin of the upper, thus relievingthe operator of the labor required to perform this portion of thelasting operation while also insuring adequate pressure -3 on the marginof the upper in the lasting of each shoe and substantially the samepressure in lasting different shoes. lhe machine herein shown is furtherso constructed that the shoe is clamped and the wipers are advancedtoward the toe by power from an initial retracted position preparatoryto the lasting operation. this being done in the first stage of a cycleof operations of the power means which then comes automatically to astop to permit the operator to operate the wipers as above described.When the power means is again started in operation the pressure isapplied to the margin of the upper by the wipers, whereupon the powermeans comes to a stop a second time with the margin under pressure. In athird and final stage of the cycle the power-operated parts are movedreversely to release the shoe.

It may under some conditions be entirely practicable, and in factpreferable, for the operator himself to apply such compacting pressureas is needed'to the margin of the upper, as well as to further providesa construction such that means movable by the operator may be used toapply the pressure without resort to power-operated means also providedfor'that purpose. As-illushated, the means movable by the operatorcomprises a treadle connected to the wipers for moving them heightwiseof the last, and the poweroperated means comprises parts which may beset to act on the wipers through the treadle connections or may, at thewill of the operator, be differently set to render them ineffective onthe Wipers in the-powercycle. I 5

Features of the invention are also to be recognized in a novelorganization of wiper-supporting and operating means, the constructionshown comprising a wiper carrier and a guide therefor pivotally mountedat one end to swing withthe wiper carrier heightwise of the shoe andeXtend-, ing within the wiper carrier, the latter being movablelengthwise of the shoe relatively tothe guide to advance the wipers overthe bottom of the shoe. As further herein illustrated the wiper carrieris thus moved lengthwise of the shoe by a hand lever mounted on theswinging guide, and mechanism is provided for imparting to the wipersclosing movements laterally of the shoe in response to the movement ofthe carrier by the hand lever.

The above and other features of the invention, including also novelmeans for controlling the shoe and various novel details of constructionand combinations of parts, will now be more particularly described withreference to the accompanying drawings and thereafter pointed out in theclaims.

The machine comprises a frame 2 on which there is secured a bracket 4having upper and lower bearings 6 and 8 for a vertically movable rod I0.Fast on the upper end of this rod is an arm I2 to which is secured aplate I4 provided with three pins I6 arranged to extend through holes inthe insole into sockets provided in metal bushings I8 (Fig. 9) in thelast to determine the position of the last and shoe in accordance withthe disclosure of United States Letters Patent No. 1,674,060, granted onJune 19, 1928 upon an application of mine. After the work has beenpresented by the operator in the position determined by the pins I6 itis clamped against the pins by a toe rest 28 which is moved upwardlyagainst the top of the forepart of the shoe and is locked againstreverse downward movement as hereinafter described, the toe restincluding a layer 22 of somewhat yieldable material such as rubber orfelt to prevent damage to the shoe upper. In the construction hereinshown the arm I2 is forced upwardly a short distance by the pressure ofthe toe rest on the shoe, the rod I0 moving upwardly with it against theresistance of. a spring 24 located between the bearing 6 and a collar 26fast on the rod and the movement being limited by engagement of a. nut28 on the rod with the bearing 8. The purpose of this is to insure thatin case the toe end of the shoe should be depressed slightly by thedownward pressure of the toe wipers on the shoe bottom, by reason of theyieldability of the part 22 of the toe rest, the pins I6 willnevertheless remain seated in the sockets in the metal bushings I8 inthe last because of expansion of the spring 24. To prevent turningmovement of the rod I0 and the arm I2 a lug 30 on the arm carries a pin32 extending downwardly into a socket in the bearing 6. While the pinsI6 thus afford convenient means adapted for use with suitably equippedlasts for positioning and holding the work, means of a differentcharacter may be used for this purpose if desired. For operating on weltshoes, for example, the arm I2'may be provided with a plate arranged toengage the bottom face of the insole and to determine the position ofthe shoe lengthwise and laterally by engaging the inner face of the lipof the insole.

The toe rest 28 is supported on the upper end of a bar 34 connected nearits upper end by a link 36 to the frame 2 and supported at its lower endby a forwardly extending arm 38 of a bellcrank lever 40 mounted to swingabout a rod 42 on the frame. The link 36 and the arm 38 are parallel toeach other, so that the bar 34 is controlled by what is virtually aparallel link arrangement and therefore is kept substantially verticalduring its upward or downward movement. The bell-crank lever 40 has adownwardly extending arm 44 through an opening in which extends a rod 46pivotally connected at its rear end to the lower end of a lever 48mounted to swing about a rod 50 on the frame. A spring 52 on the rod 46abuts at one end against a nut 54 threaded on the rod and at its otherend against a washer 56 in contact with the arm 44 of the bell-cranklever 40. Another washer 58 engaged by a nut 60 on the rod 46 serves bycontact with the arm 44 to limit expansion of the spring 52. It willthus be seen that by movement of the lower arm of the lever 48 towardthe right the bell-crank lever 40 is swung in the direction to raise thetoe rest 20, and that after the upward movement of the toe rest has beenstopped by the shoe further movement of the lever 48 will servetocompress the spring 52, the rod 46 moving relatively to the arm 44.For operating the lever 48 there is provided a path cam 62 formed in oneside of a cam wheel 64 fast on a shaft 68 operated as hereinafterdescribed, the lever carrying a roll 68 (Fig. 2) engaged by the cam.

After the toe rest 28 has been forced upwardly against the shoe throughthe bar 34 it is desirable to lock the bar positively against downwardmovement under the pressure of the wipers on the shoe. For this purposethere are provided four pawls III (Figs. 1, 4 and 5) having teetharranged in staggered relation for engagement with ratchet teeth formedon a plate I2 fast on'the bar 34. The pawls III are mounted to swingabout a rod I4 on the frame'and they are controlled by a lever I6 alsomounted on the rod I4. When the lever I6 is swung in a clockwisedirection (Fig. 1) it acts through springs I8 interposed between it andthe pawls IE! to swing the pawls into engagement with the ratchet plateI2, and when the lever is swung in the opposite direction it acts bypositive engagement with tails on the pawls to swing them away from theratchet plate. The lever 18 is controlled through a link which ispivotally connected to its lower end and extends to the left and thenupwardly close to one side of the upper arm of the lever 48. A pin 82carried by this arm of the lever 48 extends into a slot 84 in the link88, this slot having a substantially horizontal portion and an upwardlyextending portion. By engaging the link at the right-hand end of theslot 84 the pin 82 serves initially to hold the pawls I0 out ofengagement with the ratchet'plate 12, as illustrated in Fig. 1. Inoperation the pin 82 is moved to the left along the slot 84 as the lever48 is swung to force the toe rest against the shoe and arrives at theleft-hand end of the slot substantially at the time when the toe restengages the shoe. In the continued movement 'of the lever 48, wherebythe spring 52 is compressed, the pin 82 acts through the link 80 toswing the pawls into engagement with the ratchet plate so that some oneof the pawls will be in position to lock the bar 34 against downwardmovement. When the pin 82 is at the lefthand end of the slot 84 the link80 is normally prevented from swinging downwardly, even though theupwardly extending portion of the slot is over the pin, by a spring 86connected to the link and to the frame 2. Before the lever 48, however,begins its reverse movement to return the toe rest to starting position,the link 80 is swung downwardly about its connection with the lever I6,to cause the pin 82 to enter the upwardly extending portion of the slot84, by a cam 88 formed on the hub of the cam Wheel 64 and engaging afiat face 90 on the link. Accordingly, the lever 48 at the beginning ofits reverse movement acts through the link 80 to retract the pawls 10 soas to permit the lowering of the toe rest. After the pawls have beenretracted from the ratchet plate 12 the cam 88 releases the link.

and permits it to be swung upwardly by the spring 86, so that in thecontinued movement of the lever 48 the pin 82 is returned to therighthand end of the slot 84.

For wiping the toe end of the upper heightwise of the last and wipingits margin inwardly over an insole on the last there are provided wipers92 detachably mounted on wiper holders 94 which are supported on a wipercarrier 96. The wiper holders have curved tongue-and-groove connectionswith the wiper carrier, as indicated at 98 (Fig. 3), whereby the holdersand the wipers are guided for swinging or closing movements laterally ofthe shoe as they are advanced lengthwise of the shoe by movement of thewiper carrier.

The wiper carrier 96 has a cover plate I00 fast on the top thereof, andextending forwardly within the carrier under the cover plate is a barI02 which serves as a guide for the carrier in the movements of thelatter lengthwise of the shoe. At its left-hand end the bar I02 hasspaced bearing portions I04 pivotally" mounted on a rod I06 which issupported in the upper end of a double link I08 pivotally mounted at itslower end on a rod IIO on the frame and controlled as hereinafterdescribed. The wiper carrier 96 near its right-hand end is supported bya link II2 constructed as also more particularly hereinafter describedand extending downwardly from it to a short crank arm II4 controlled bya double-acting treadle II 6 which is mounted on a rod I I8 on the frame2. By movements of the treadle II 6 the wiper carrier may be swungupwardly and downwardly with the guide bar I02 about the rod I06 tocause the wipers to wipe the upper heightwise of the last and later topress its overwiped margin down on the insole.

It will be understood that as the wiper carrier 96 is moved lengthwiseof the shoe along the guide bar I02 the link II2 swings about itsconnection with the crank arm II4. For imparting such movement to thewiper carrier there is provided a hand lever I20 pivotally mounted atits rear end on the lower end of a bolt I22 in the guide bar I02 andconnected by a link I24 to the wiper carrier underneath the latter. Thehand lever I20 is further supported by the upper face of a curved barI26 fast on a bracket I28 which is secured at its left-hand end to aportion of the bar I02 and at its right-hand end to an arm I30 extendingforwardly from the bar I02 through an opening I32 in the wiper carrier96. The curved bar I26 is also arranged to cooperate frictionally withan arm I34 pivotally mounted on the hand lever I20 to hold the handlever against reverse movement toward the left after it has been movedtoward the right to operate the wipers, as common in lasting machines ofthe bed type. The arm I34 is recessed at I36 to receive the bar I26 andis urged by a spring I38 in the direction to bind on the bar I26 andthereby prevent movement of the hand lever toward the left althoughpermitting it tomove toward the right. When the operator wishes to movethe hand lever toward the left he releases it by well-known means notfully shown but including a lever I40 which by engaging the arm I34swings the latter into position to release its grip on the bar I26.

To facilitate movements of the wiper carrier 96 by the hand lever I20there are provided a plurality of rolls to minimize friction. Mounted onthe rod I06 between the spaced bearing portions I04 of the bar I 02 is aroll I42 arranged to be engaged underneath by an extension I44 of thewiper carrier 96 and to be engaged above by an extension I46 of thecover plate I00. Near its left-hand end the bar I02 is engaged on itsopposite sides by rolls I48 mounted on studs I50 on the wiper carrier,and at its right-hand end the bar carries a pin I52'on which are mountedtwo rolls I54 arranged to engage fiat faces I56 on the wiper carrier 96underneath and similar faces on the cover plate I00 above. Near itsright-hand end the bar I02 is provided with lateral extensions I58 onwhich are formed plane vertical faces I60 engaged by rolls I62 mounted vto turn about studs I64 on the wiper carrier 96. It will thus be seenthat anti-friction means is provided for supporting the wiper carrieragainst lateral thrust and against thrust in an upward or a downwarddirection.

The wiper holders 94 are operated to close the wipers laterally of theshoe by that movement of the wiper carrier 96 whereby the wipers areadvanced lengthwise of the shoe. For this purpose the wiper holders areprovided with teeth I66 engaged by gearsectors I68 which are mounted toturn about the studs I64 above the rolls I62 and are connected throughsleeves thereon to other gear sectors I10 below the rolls, the rollsbeing mounted on the sleeves. The gear sectors I10 are in engagementwith rack bars I12 mounted in blocks I14 secured to the lateralextensions I58 of the bar I02, the rack bars being movable in the blocksin directions lengthwise of the shoe. Normally, however, the rack barsare held against any such movement by springs I16 which bear at theirright-hand ends against shoulders on the blocks I14 and at theirleft-hand ends against lugs I18 extending upwardly from the rack bars,and by pins I mounted in the extensions I58 of the bar I02 and engagingthe lugs I18 on the opposite sides from the springs. Accordingly,

as the wiper carrier 96 is moved toward the right by the hand lever I20to advance the wipers lengthwise of the shoe the relatively stationaryrack bars I12 cause the gearsectors I10, I68 to turn and thereby toswing the wiper holders 94 and close the wipers laterally of the shoe.In

case either of the wipers encounters abnormal.

resistance to its closing movementhbefore the wipers have been advancedas far as desired lengthwise of the shoe, the rack bar I12 connected tothat wiper will move with the wiper carrier 96 against the resistance ofits spring I16 so that no further closing movement of that wiper willtake place as the wipers are further advanced.

' arm connected to the double link I08 which, as

previously described, supports the left-hand end of the guide bar I02and the left-hand end of the wiper carrier 96. The lower arm of thelever I82 carries a roll I84 engaged by a path cam I86 formed in oneside of the cam wheel 64. For connecting the upper arm of the lever[82,170

the link I88 there is provided a shaft I88 thread"- ed at one end in atrunnion block I90 carried by the lever I82 and swiveled in anothertrunnion block I92 carried by the link I88. A collar I93 fast on theshaft I88 atone end of this trunnion block and an enlarged portion I94of the shaft at the other end of the trunnion block cause any lengthwisemovement of the shaft to be accompanied by swinging movement of the linkI88. On the outer end of the shaft I88is a hand wheel I95 for turning itto swing the link I88 relatively to the lever I82 and thereby to-adjustthe wiper carrier 86 preliminarily lengthwise of the shoe. The advancemovement of the wiper carrier 96 effected by the lever I82 occurs uponthe starting of the power operation of the ma chine substantially at thetime when the toe rest 28 is moved upwardly to clamp the shoe, afterwhich the machine comes to a stop to permit the operation of the wipersby the hand lever I26 and the treadle II6.

In operating, for example, upon shoes the up pers of which are made ofcomparatively heavy material it may be desirable to apply more downwardcompacting pressure to the overlaid margin of the upper than theoperator can easily apply by use of the treadle H8. The machine isaccordingly further provided with power means which at the will of theoperator may be made to act through the link II2 to apply downward forceto the wiper carrier 98 after the wipers havebeen operated to wipe themargin of the upper inwardly over the insole and while they are over theshoe bottom. The link II2 includes a member I 96 pivotally connected tothe wiper carrier 96 and in which is threaded the upper end of a rod I98the lower end of which is threaded in another member 208 pivotallyconnected to the crank arm H t. A direct positive connection is thusprovided between the wiper carrier and the treadle II6 for swinging thewiper carrier by the use of the treadle. A nut 282 threaded on the rodI98 near its upper end serves by engagement with the frame 2 to limitdownward movement of the wiper carrier. The lower portion cf the rod I98is reduced in diameter to provide at the lower end of its larger portiona shoulder engaged by a thimble 288 slidingly mounted on the lowerportion of the rod, and between this thimble and another thimble 286adjustably threaded on the rod is a compression spring 298. slidinglymounted on the larger portion of the rod 1 98 and abutting at its lowerend against the thimble 28 3 is a sleeve 2I0, and surrounding thissleeve with its lower end in engagement with the thimble 284 is acomparatively light spring 2I2. The upper end of the spring 2I2 bearsagainst a block.2l4 slidingly mounted on the rod I98. Pivotallyconnected to the block 2 I8 is one link2 I 6 of a. toggle, this linkbeing pivotally connected by a pin 2 I8 to another toggle link 228 whichat its upper end is pivotally connected to one arm of a lever 222mounted on a rod 224. The lever 222 has another arm which carries a roll226 engaged by a path cam 228 (Fig. '7) formed in one side of a camwheel 238 fast on the shaft 68. Extending to the right from the togglelink 2E6 is a handle 232. As the parts are shown in Fig. 1 the toggle isbroken and is maintained in thisbroken condition by the spring 2 I2which supports the block 2 I4 at a considerable distance above the upperend of the sleeve 2 I ll. When the operator raises the rod I98 by thetreadle I I6 to cause the wipers to wipe the upper heightwise of thelast the springs 298 and 2I2 are, of course, moved upwardly with it,

and the block 2I4, with the toggle broken as above described, is furtherelevated through the spring 2 I2, the two toggle links 2 I 6 and 220swinging idly farther in a left-hand direction. It will beunderstoodthat the toggle still remains in a broken condition when theoperator, after the overwiping operation, forces the wipers downwardlyon the shoe bottom by the treadle, and such movement as the lever 222thereafter receives from the cam 228 when the cam shaft 66 is againstarted in operation only results in swinging the toggle links idly in aleft-hand direction.

If the operator desires that the wipers'be operated by power to applydownward compacting pressure to the margin of the upper he forces-thehandle 232 downwardly prior to the use of the machine on a shoe andthereby swings the toggle links 2 I 9, 220 to the right to straightenthe toggle, the block 2I4 being thereby forced downwardly against theresistance of the spring 2I2. The toggle links are, in fact, swungslightly beyond positions of parallelism so as to insure that'the togglewill maintain its straightened condition until again broken by theoperator, the swinging of the links being limited by engagement of ashoulder 234 on the link 220 with a shoulder 238 on the link 2 I6. Theblock 2 I4, although forced downwardly as above described, is stil farenough above the upper end of the sleeve'2I8 to permit the operator toraise the rod I98 by the treadle I if; as far as necessary to wipe theupper heightwise of the last. It will be understood that the operatorthen advances and closes the Wipers as usual to wipe the margin of theupper over the insole. .When the lever 222 is thereafter operated by itscam it acts through the straightened toggle to force the block 2 I4downwardly, and this block acts through the sleeve 2 I 8, the thimble284and the spring 288 to apply downward force to the rod I98 and thereby tocause the wipers to apply heavy downward pressure to the margin of theupper, the spring 208 being compressed more or less in this operation. i

The cam shaft 66 may be driven and controlled by any suitable means. Inthe construction shown there is fast on-this shaft a worm gear 238operated by a worm 240 fast on a shaft 242 at right angles to the shaft66, the shaft 242 having fast on its left-hand end one member 244 of acone clutch. Arranged to cooperate with the clutch member 244 is anotherclutch member 246 mounted to turn on and to slide lengthwise of theshaft 242, this clutch member being driven continuously through sprocketwheels and a chain 248 by an electric motor 258. The clutch member 246is normally held out of contact with the member 244 by a spring (notshown) located between these members. To force the member 246 intoclutching engagement with the member 244 there is provided a verticallymovable forked wedge member 252 in the lower end of which there is avertically elongated slot 254 (Fig. 2). Extending through this slot is ashaft 256 mounted in the forked left-hand end of alever 258 which ismounted to swing about a rod 260 supported on the frame 2. ,Threaded inthe lower end of the wedge member 252 is a screw 262 (Fig. 2) the upperend of which is arranged to enter a recess 264 in the shaft 256 when thelefthand arm of the lever 258 is swung downwardly, the wedge member 252being then moved down wardly by contact of the shaft 255 with the end ofthe screw to start the power operation of the machine. The lever 258 isoperated by a treadle 266 mounted on the rod H8 and from thelefthand endof which a link 268 extends upwardly, this link carrying a plate 218 theupper edge of which is arranged normally to underlie a plate 212 on theright-hand arm of the lever 258. It

' will thus be seen that when the treadle is depressed the lever 258 isswung to start the maserves to hold the link 268 in the normal positionchine as above described by the upward pressure of the plate 218 on theplate 212. A spring 214 connected to the upper end of the link 268 andto a short arm 216 on the hub of the lever 258 illustrated in Fig. 1. 7

Fast on the shaft 242 is a brake drum2'l8 (Fig. 2) arranged to beengaged on its periphery by two brake shoes 288-and 282 pivotallyconnected together by a pin 284. Pivotally mounted on a stud 286 on theframe is a lever 288 connected at its left-hand end (Fig. 2) below thestud 286, by

-means of a link 298, to one end of the brake shoe 20.

288. A'link 292 is pivotally connected to one end of the other brakeshoe 282 and extends through an opening in a pin 294 swiveled in theleft-hand end of the lever 288above the stud 286. A block 296 adjustablythreaded on the link 292 near the upper end of the link is arrangedtoengage a flat face on the pin 294. It will thus be seen that when theright-handend of the lever 288 (Fig. 2) is swung upwardly the brakeshoesare forced against the brake drum to stop rotation of the shaft 242 andthat when this end of the lever is moved downwardly the pressure of thebrake shoes on the brake drum is relieved. The lever 288 is controlledthrough a link 298 by a lever 388-(Fig. 6) mounted to turn on the rod268, this lever being adjustably connected to the lever 258 by a pin 382eccentrically mounted on one end of the shaft 256 and rotatable in ablock 384 which is slidingly mounted in a slot 386 (Fig. 6)' in thelever 388. It will thus be seen that when the lever 258 is operated asabove described by the treadle 266 to start the machine the lever withit to apply the brake. Swinging movement of the levers 258 and 388inthis direction is effected by a spring 388 connected at its upper endto a pin on theframe and at its lower end to a pin on the lever 388.

It will be evident that when the lever 258 is swung in the direction tostart the machine it does not become effective on the wedge member 252until it has been moved far enough for the screw 262 to be engaged bythe shaft 256 at the bottom of the recess 264 in the shaft. This insuresthat the brake will be released before the clutch is actuated. By meansof a handle 3| 8 fast on the shaft 256 the shaft may be turned through180 to bring another deeper recess 3l2 therein opposite the screw 262and by such turnof the treadle being limited by'contact with the floor.Insurance is thus afforded against any accidental starting of themachine. A springpressed ball 3M mounted in the lever 258 and arrangedto enter one or the other of two depressions in the hub of the handle3l8 serves to maintain the shaft 256 yieldingly in either position towhich it is moved by the handle.

After the machine has been started by depression of the treadle 266 itis brought automatically to a step. For this purpose there is fast onthe shaft 66 a stop cam 316 (Figs. 2 and 8) the periphery of which is inengagement with a roll 3E8 carried by an arm 328 extending upwardly fromthe hub of the lever 258. The roll 3l8 lies normally in a depression 322in the cam 3l6, out of which depression it is carried by the movement ofthe lever 258 in the direction to start.

the machine. Thereafter the cam 3l6 maintains the lever 258 in theposition to which it was moved by the treadle until a second depression326 in the cam arrives opposite the roll 3l8, whereupon the spring 388acts to swing the lever 258 in the direction to stop the machine. Inorder that the machine will be stopped even though the operator shouldcontinue to hold the treadle 266 depressed, there is further providedmeans for automatically swinging the link 268 to the right, as the partsare viewed in Fig. 1, to carry the plate 218 out from under the plate212. This means comprises a lever 326 (Fig. 8) pivotally mounted on theframe and having at one end a roll 328 for engaging the link 268, theother end of the lever being located in the path of a pin 336 upon oneside of the stop cam 355. It will be understood that shortly after themachine is started this pin swings the lever 326 for the purposedescribed and then passes beyond the end of the lever. The stop cam 3 l6has in its periphery also another depression 332 for bringing themachine to a stop a second time before the end of the cycle, as moreparticularly hereinafter explained, and it carries other pins'334 and336 for operating the lever 326, as required at different times, in thesame manner as the pin 368. When the operator releases the treadle 266it is returned by a spring 338 (Fig. 1) connected to the link 268, itsreturn movement being limited'by contact of a stop screw 388 carriedthereby with a boss 342 on the frame. a d

In the use of the machine the'operator mounts a last and shoe on thepins I6 and depresses the treadle 266 to start the power operation ofthe machine. Upon the starting of the machine the toe rest 28 is raisedto clamp the work against the pins "5 and is locked by the pawls. 18,the arm l2 being forced upwardly a short distance by pressure of the toerest on the shoe until the nut 28 engages the bearing 8. Atsubstantially the same time the wiper carrier 96 is moved to carry thewipers 92 from their initial position toward the toe end of the shoe.Thereafter the machine comes to a stop as the recess 324 in the stop cam316 arrives opposite the roll 318. By use of the hand lever I28 theoperator then advances and closes the wipers about the toe belowthe edgeof the shoe bottom as illustrated in Fig. 9, and while holding themagainst the upper by the hand lever he raises them by means of thetreadle H6 to wipe the upper upwardly. By further movement of the handlever the operator thereafter operates the wipers to wipe the margin ofthe upper inwardly over the insole, controlling them at the same time bythe treadle H6 and, it may be, forcing them down more or less by thetreadle. If an adhesive is to be used to secure the toeend of the upperto the insole, the wipers may then be withdrawn from over the shoe andthe margins of the lining and the toe box trimmed as-is'customary inlasting with adhesive, after which a suitable adhesive may be applied tothe margin of the outer layer of the upper materials and to the insole.The operator then uses the wipers again to wipe the upper upwardly andto wipe its margin inwardly over the insole. If the character of thework is such that it is desirable to operate the wipers by power topress the margin of the upper down upon the insole, the operator willhave used the handle 232 to straighten the toggle 2H5, 220 beforepresenting the shoe to the machine. With the wipers engaging the marginof the upper over the insole, as illustrated in Fig. 10, the treadle 15'266 is depressed a second time, whereupon the lever 222 acts through thespring 208 to force the wipers downward and thus to increase theirpressure on the margin of the upper, the machine coming to a stop'whenthe recess 332 in the stop cam 3l6 arrives opposite the roll 318. Ifpower is not to be used to press the margin of the upper, the toggle'2l6, 220 is left in its broken condition and the wipers are forced downonly by the operator through use of the treadle H6. Under theseconditions, when the machine is started the second time, the lever 222merely acts to swing the toggle links without effect on the wipercarrier 96. In either case a third depression of the treadle 266 resultsin return of the power-operated parts to their starting positions andrelease of the shoe. It will be understood that even if power is used toforce the wipers downward, they may be forced downward more or less bythe treadle before the power is applied.

If the upper materials are to be secured to the insole by drivenfastenings, the operator may partially retract the wipers and drive suchfastenings after wiping the margins of the several layers of uppermaterials over the insole and pressing them down by use of the treadleH6. The wipers may, if desired, then be moved farther inwardly by thehand lever and forced down by the power means upon the second startingof the machine if the parts are positioned for the use of such powermeans. If the downward pressure of the wipers on the shoe, either by theaction of the treadle H6 or by power, should result at any time in anydepression of the forepart of the shoe and last by reason, for example,of the yieldability ol the rubber or felt portion 22 of the toe rest,the spring 24 expands to impart a corresponding downward movement to thearm l2 and thus to maintain the pins i6 seated in the sockets in thelast.
